Trapping gases better with boron nitride "nanopores"
What is common between a technology for storing energy in a solar cell and that for water purification? They both rely on the use of porous materials, or more specifically, 'nanoporous' materials that can trap gas molecules within narrow spaces on th.....»»
Cattle manure biochar could offset earthworm greenhouse gas emissions in forest soil
As two important greenhouse gases, about 20% and 62% of global carbon dioxide (CO2) and nitrous oxide (N2O) emissions originate from the soil, especially agricultural and forest soils. Therefore, it is necessary to explore sustainable management stra.....»»
Chemical engineers use neural networks to discover the properties of metal-organic frameworks
Metal-organic frameworks, a class of materials with porous molecular structures, have a variety of possible applications, such as capturing harmful gases and catalyzing chemical reactions. Made of metal atoms linked by organic molecules, they can be.....»»
Time is running out to counteract global climate change
The increase in emissions of greenhouse gases into the atmosphere is only one of several serious global threats to our continued existence on Earth, and their reduction is at the core of international agreements like the Paris Agreement and the UN Su.....»»
China chip firms expand investment in GaN semiconductors
China-based semiconductor companies, including Innoscience, Sanan Optoelectronics, and Enkris Semiconductor, are stepping up their investment in GaN (gallium nitride) power semiconductors and adding new production lines......»»
Specialty gas provider Ingentec plans Taiwan OTC listing in April
Ingentec, which specializes in specialty gases for chipmaking, will be listed on the Taiwan over-the-counter (OTC) stock market in mid-April, after it posted robust revenue growth in 2021......»»
Cameras reveal snowshoe hare density
A new study in the Journal of Mammalogy shows recently developed camera-trapping methods could be a viable alternative to live-trapping for determining the density of snowshoe hares and potentially other small mammals that play a critical role in a.....»»
Climate mitigation measures could impact food security
Many countries have set carbon neutrality as a policy goal, but according to a new study by an international team of researchers from IIASA, Japan, and the U.S., there are various risks associated with the reduction of greenhouse gases, especially in.....»»
Scientists help recover gases from moon rock time capsule
Scientists from Washington University in St. Louis are helping to recover gases from a container of lunar soil that astronauts collected and sealed under vacuum on the surface of the moon in 1972. The effort is part of NASA's Apollo Next Generation S.....»»
Low on gas: Ukraine invasion chokes supply of neon needed for chipmaking

Stalled weather: How stuck air pressure systems drive floods and heatwaves
Climate change—fuelled by increasing greenhouse gases—is causing more extreme weather events worldwide......»»
How one marine chemistry lab slashed their carbon footprint
Laboratories may consume large quantities of plastics, generate waste, and emit greenhouse gases. A report published in PLOS Sustainability and Transformation by Jane Kilcoyne and her colleagues at the Marine Institute, Galway, Ireland exemplifies ho.....»»
Biden administration wants Chinese tech companies to aid in export controls against Russia
Several countries in Europe started imposing additional sanctions on Russia last week in response to its invasion of Ukraine, prompting some in the semiconductor industry to look for alternative suppliers for materials and gases needed at their chip.....»»
How do marine gases affect cloud formation?
Studying the global climate—and how it's changing—involves examining thousands of small processes, chemical mechanisms, local weather phenomena, and more. One of the many factors scientists consider when studying the changing climate is aerosols,.....»»
NASA develops technology to dissect the lower atmosphere
The part of the atmosphere closest to the planet is the hardest to measure from space due to the volume of gases above it. Studying Earth's planetary boundary layer, or PBL, will enable scientists to better understand the interaction between Earth's.....»»
GaN Systems scales up operation in Taiwan
GaN Systems, which specializes in GaN (gallium nitride) power semiconductors, has moved to beef up its operation at the Hsinchu Science Park (HSP), northern Taiwan to satisfy robust demand from the Asia market, according to the fabless company headqu.....»»
The first observation of oxygen-oxygen bond formation by a low-valent RuIII complex
Currently, the world's energy demand mainly depends on fossil fuels being a limited resource. The consumption of fossil fuels leads to emission of carbon dioxide (CO2) that is one of the major greenhouse gases contributing to global warming and clima.....»»
Battery-powered trains are picking up speed
Electric locomotives could cut emissions of greenhouse gases, toxic pollutants. Enlarge (credit: Wabtec) Battery-electric power is commonplace in cars and trucks and is being tested in planes, helicopters, and container ships.....»»
Underwater "breathing" plants could be key to stress-resistant crops
Wetland plants have a high tolerance against flooding due to the formation of "lysigenous aerenchyma," air channels that help transfer gases to the submerged roots. These channels also help the plant withstand drought and nutrient deficiency. Now, sc.....»»
Olympic ice rinks put spotlight on potent greenhouse gases
The ice rinks that play host to figure skating and speedskating competitions at the Beijing Olympics will also be putting a major environmental problem on the world stage—the potent greenhouse gases often lurking in refrigerators, air conditioners.....»»
Phasing out animal agriculture could potentially stabilize greenhouse gas levels for decades, according to new model
The worldwide phase out of animal agriculture, combined with a global switch to a plant-based diet, would effectively halt the increase of atmospheric greenhouse gases for 30 years and give humanity more time to end its reliance on fossil fuels, acco.....»»
